TECHNICAL FIELD

The present invention relates to a fitness apparatus for training the human body.

BACKGROUND

For many people, sport is an essential part of their lives. Especially for a healthy physique, to strengthen the human muscles and to improve and maintain the physiological condition of the human body, a sporting activity is essential in everyday life.

Against this background, sport training methods are also frequently used for the rehabilitation of injuries and/or operations on the human body. In particular, such training methods may prevent or alleviate pain, especially by developing the muscles.

In recent years, functional training methods have become increasingly popular, especially for a sound, balanced and holistic physical health. Here, the focus of training is on as free and natural movements of the human body as possible. First, individual structures are improved in isolation. Subsequently, these structures are re-integrated into large movement sequences in order to then move as freely and unrestrictedly as possible again.

As a result, machine-guided movements are increasingly being dispensed with and free and natural movements are being performed instead. As a result, /the human body is holistically worked, which in turn causes a balanced and ideally dosed development of the muscles to prevent injuries.

Training apparatuses, for example in the form of free weights, which can be moved freely in the room, are well-known. However, such free weights entail a considerable potential for injury. For example, many injuries are caused because of the completely free movement of free weights in the room and/or because of improper use of these training apparatuses.

Another well-known training apparatus is the so-called landmine, which comprises an anchor attached to the ground that holds a weight bar. By means of a joint attached to the anchor, the weight bar can be swiveled around the anchor. However, because of its attachment to the ground, the landmine imposes an unnatural motion that is not used much in everyday life, which in turn limits the usefulness of the motion. For example, every movement is on a circular arc with a radius equal to the length of the weight bar, about the attachment point located on the ground. The landmine is also limited in terms of the variety of exercise movements that can be performed. In addition, the weights must be slid onto the weight bar in a bent posture, which places a significant strain on the user's back.

SUMMARY

Therefore, it is an object of the present invention to overcome the disadvantages of the prior art or at least to provide an alternative and, in particular, to improve the holistic training of the human body.

This object is achieved with the subject-matters of the independent claims. Advantageous embodiments with expedient further developments of the invention are specified in the respective dependent claims and in the following description.

The invention relates to a fitness apparatus for training the human body. The training apparatus comprises a support member having a fastening member arranged at a first end of the support member for fastening the support member to a support structure, preferably an overhead support structure, and more preferably to a ceiling of a room, a weight bar for receiving at least one weight having a free end and a mounted portion. The mounted portion is preferably provided at the end of the weight bar which is opposite the free end. The training apparatus further preferably comprises a bearing member which receives the mounted portion of the weight bar and connects the weight bar to a section of the support member which is spaced apart from the first end, preferably the second end opposite the first end.

The weight bar is movable in at least two planes, the at least two planes comprising a plane which extends perpendicularly to the longitudinal axis of the support member (e.g., a horizontal plane) and a plane in which the longitudinal axis of the support member extends (e.g., a vertical plane). Preferably, the weight bar is further rotatably mounted about its longitudinal axis, preferably by the support member. Furthermore, the support member is elongated and preferably has a length of at least 100 cm.

The fastening of the support member to a support structure, preferably to an overhead support structure, preferably to the ceiling of a room, allows a suspended attachment of the support member. The first end of the support member thereby corresponds to the upper end and the second end corresponds to the lower end. As used herein, support structure means a structure that allows such a suspended attachment of the support member. An overhead support structure preferably allows the first or the upper end of the support member, respectively, to be attached at a position that is at the head height or above the height of a user's head. Preferably, this may also include the height of a user's shoulder region. As described below, the support member is preferably adjustable in length or interchangeable with a support member of different length.

The fastening of the support member at a support structure, preferably an overhead support structure, preferably the ceiling of a room, firstly results in a good stowability of the fitness apparatus. For example, after use thereof, the fitness apparatus can be moved into a position, e.g., by displacement, swiveling, rolling up or other stowing of the support member, that does not, or only slightly, interfere with the training area when the fitness apparatus is not in use. In particular, the ground area underneath the fitness apparatus is freely accessible and without obstruction.

Furthermore, the fastening of the support member to an overhead support structure simplifies the sliding of weights onto the weight bar, as this allows the weight bar to be placed in a position that is more manageable for people, and thus the risk of injury to the user is also reduced.

Furthermore, a high and flexible degree of freedom of movement during training is made possible by the fastening of the support member at an overhead support structure together with the mobility of the weight bar in at least a plane transverse to the longitudinal axis of the support member and in a plane in which extends the longitudinal axis of the support member, as well as, preferably, by the rotatability of the weight bar about its longitudinal axis. This provides the user with a wide range of movement options that make possible therapies and training options for many body areas.

In addition, the training apparatus according to the invention, and, in particular, the fastening of the support member at an overhead support structure, allows to perform pendular movements of the weight bar, of the weight received by the weight bar, of the bearing member, and the support member, about the fastening point at the overhead structure. On the one hand, such pendular movements cause instability of the weight bar when performing the training movements, which must be compensated for by the user's muscles. In this regard, a length of the support member of 140 cm and/or a maximum length of the support member of 300 cm is particularly advantageous.

Furthermore, after a deflection of the weight bar has been performed, such pendular movements produce a restoring force directed against the deflection movement direction, which, depending on the position of the user relative to the deflection, produces a dynamic or static compressive or tensile force exerted on the user. These dynamic or static compressive or tensile forces thus lead to a further or alternative type of stress on the user's muscles.

The extent of the pendular movements and the resulting restoring force may, in particular, be controlled via the size of the deflections of the weight bar. Consequently, smaller deflections also result in lower dynamic or static pressure or tensile forces exerted on the user. Furthermore, the resulting restoring force can be controlled via the weight force of the weight bar, the weight received by the weight bar, the bearing member and/or the support member. Advantageously, the corresponding restoring force can also be adjusted by additional weights described herein, e.g., leveling counterweights.

The elongated design of the support member and, in particular, its minimum length of 100 cm, allows the weight bar to be provided at a height that, depending on the height of the overhead support structure above the ground of the room, enables a variety of overhead exercises and exercises that are performed below the user's eye level. The adaptability and customizability of this advantage to different users or groups of users is supported, in particular, by the adjustability of the length of the support member and/or its interchangeability with a support member of different length.

In an advantageous embodiment, the support member is flexible and is preferably configured as a rope, band or belt. In view of the flexibility and the lower stability of the support member (especially with regard to twistability and bendability), the possible movements of the weight bar are increased. This is accompanied by less guidance of the weight bar by the support member, in particular in a plane which extends perpendicularly to the longitudinal axis of the support member. The reduced stabilization by the support member must instead be compensated for by the user's muscles, which results in a further strengthening of the muscles, in particular the stabilizers. In this way, the muscles of various body areas can be built up in a targeted and gentle manner Δt the same time, it is possible to realize a variety of natural movement sequences which are not restricted by the structure of the fitness apparatus.

Alternatively, the above-mentioned advantages may also be achieved by configuring the support member as a bar that is pivotally connected at its first, upper end and its second, lower end to the fastening member or the weight bar, respectively, in such a way that corresponding degrees of freedom are made possible. For example, by universal joints or ball joints. In this embodiment, merely a vertical movement of the mounted end of the weight bar is not possible.

Preferably, the weight bar mounted in the bearing member is a rigid body and has three rotational and three translational degrees of freedom in space.

Thus, on the one hand, the weight bar can be tilted in a plane in which the longitudinal axis of the support member extends (e.g., a vertical plane) solely based on the flexible properties of the support member. On the other hand, the weight bar can be pivoted about the longitudinal axis of the support member in a plane which extends perpendicularly to the longitudinal axis of the support member (for example, a horizontal plane). Further, the weight bar may be rotated about its own longitudinal axis. Finally, due to the flexible properties of the support member, the weight bar can be moved translationally in all three spatial directions. Merely the vertical downward movement is restricted by the set length of the support member.

In an advantageous embodiment, the fitness apparatus may additionally comprise a leveling counterweight, for example a housing, in which the bearing member is arranged, the leveling counterweight or the housing or the bearing preferably, respectively, having a weight of at least 3 kg, further preferably at least 5 kg and preferably at least 10 kg. The leveling counterweight is preferably arranged at the lower end of the support member.

By providing a minimum weight of the leveling counterweight, the flexible support member may be provided with a desired basic stability so as to influence the deflection sensitivity of the support member. For example, if the leveling counterweight is set at 10 kg, the support member will have less deflection sensitivity due to the weight force of the leveling counterweight acting on the support member than with a leveling counterweight having a weight of 5 kg. Thus, by means of the selected weight, the desired basic stability of the support member can be set. The weight, which is slidably arranged on the weight bar, also impacts the restoring force. It also supports the leveling counterweight, both when it is pushed all the way against the housing and when it is some distance away. Preferably, the position of the weight on the weight bar is thus specifically selected.

Furthermore, by varying the selected leveling counterweight, the magnitude of the restoring force caused by pendular movements of the fitness apparatus including the leveling counterweight may additionally be controlled after a performed deflection of the weight bar. Preferably, the support member, the bearing member and/or the housing is configured to receive additional weights in order to vary the total leveling counterweight. Thus, by varying the total leveling counterweight, it is possible to individually adjust the stability of the support member.

In an advantageous embodiment, the fastening member is configured for rotatable fastening of the support member. In this way, the weight bar may be rotated about the longitudinal axis of the support member, which allows a higher degree of freedom of movement of the weight bar and thus a high degree of flexibility in the training options. Further, this increases the stowability of the fitness apparatus during non-use.

Preferably, the fastening member for a rotatable fastening of the support member is designed as a swivel carabiner or universal joint. Preferably, the only “fixed” bearing, i.e., a bearing not having several degrees of freedom or preferably only two degrees of freedom and further preferably only one degree of freedom, is the bearing of the weight bar, which is preferably configured as a ball bearing. The remaining degrees of freedom are preferably made possible by the flexibility of the belt (inclination at both ends and torsion over the entire belt).

In an advantageous embodiment, the weight bar has a training weight receiving or displacement section extending along at least a portion of the length of the weight bar, along which the training weights to be received are displaceable.

Due to the displaceability of the training weight(s) to be received along the displacement section, it is possible to adjust the lever arm of the weight bar, which extends from the position of the weights received on the weight bar to the section of the weight bar mounted in the bearing member. Consequently, in addition to the number and/or size of the weights to be received, the training load may also be controlled by the lever arm of the weight bar, which increases flexibility in determining the training load and thus the training options. This also simplifies and improves the individualization of settings for a specific user or group of users. In addition, this makes it possible to flexibly vary the gripping points of the weight bar at which the user grips the weight bar.

The fitness apparatus may additionally comprise at least one locking means displaceable along the displacement section, by means of which the weight(s) to be received can be locked in a position along the displacement section.

Further, the length of the training weight receiving range or displacement section may be at least 50%, preferably at least 75%, and more preferably 75% to 80% of the total length of the weight bar.

The displacement section may preferably extend from the free end of the weight bar.

In another advantageous embodiment, the bearing member comprises a ball bearing to allow rotatability of the weight bar about its longitudinal axis.

This allows a stable bearing of the weight bar in the bearing member and, at the same time, increased flexibility of the weight bar's movement options.

Alternatively, the bearing member may have a slide bearing.

In order to make the resistance of the weight bar also more flexible, the fitness apparatus may additionally comprise an elastic band that may be fixed to the weight bar and to an anchor member fastened to a fastening structure to thus provide variable resistance over the range of motion of the weight bar.

An elastic band has the property that its tensile resistance increases with increasing elongation of the elastic band. Thus, the elastic band, which can be fixed to the weight bar and to an anchor member fastened to a fastening structure, has the effect that the resistance of the elastic band, and thus also the total resistance of the weight bar, is lower in case of a low deflection of the weight bar than in case of larger deflections of the weight bar. In this way it is possible to dynamically vary the total resistance of the weight bar over the entire range of motion of the weight bar. The elastic band may be provided additionally, or alternatively, to the provision of training weights. Furthermore, the fastening structure for the elastic band may be provided below, above, and/or to the side of the weight bar. In this way, the resistance provided by the elastic band can be optimally aligned and adjusted. For this purpose, for example, an adjustment ring can be provided which is formed on the weight bar or which can be fastened to the weight bar, where the elastic band may be passed through the adjustment ring for fastening to the weight bar.

In a further advantageous embodiment, the fitness apparatus additionally comprises an adjustment mechanism by means of which the length of the support member can be adjusted.

On the one hand, in this way it is possible to adjust the height of the weight bar above the ground. In particular, however, this also makes it possible to adapt the fitness apparatus to different heights of the overhead support structure above the ground of the room, in particular to different ceiling heights of the room, in order to set the desired height of the weight bar above the ground.

The adjustment mechanism may be a component of the support member, in which case the adjustment mechanism is arranged along the length of the support member. However, it is also conceivable that the adjustment mechanism is formed or molded onto the bearing member and/or onto the fastening member for fastening the support member to an overhead support structure. In a preferred, easy-to-implement variant, the support member is configured as a belt or rope and the adjustment mechanism is provided as a type of belt or rope tensioner. This can take the form of a belt buckle, as is known, for example, from backpacks or the like. The adjustment mechanism can preferably be placed along the belt.

Alternatively, it is also preferred that the adjustment mechanism is configured such that the support member has a plurality of segments, wherein segments can be removed to shorten the length of the support member or added to lengthen the support member. Preferably, at least one basic segment has a length of at least 30 cm, preferably at least 50 cm, more preferably at least 70 cm, and more preferably at least 100 cm. This basic segment may provide a basic length of the support member, wherein further extension segments may be added in a modular manner to extend the support member, which extension segments may have different lengths of, preferably at least 10 cm, more preferably at least 20 cm, more preferably 40 cm, more preferably 50 cm.

Preferably, the weight bar has a length extending between the mounted area and the free end of the weight bar, which length is adjustable.

Preferably, the length of the weight bar extending between the mounted area and the free end of the weight bar is adjustable in that the weight bar is displaceable by the bearing member and preferably lockable in individual positions.

This creates a further possibility to adjust the lever arm of the weight bar and thus the training load of the weight bar. When the weight bar is pushed through the bearing member, part of the total length of the weight bar extends beyond the receiving surface of the bearing member. In this situation, the usable length of the weight bar that extends between the mounted portion and the free end of the weight bar deviates from the total length of the weight bar. If no part of the length of the weight bar extends beyond the bearing member, then the usable length of the weight bar that extends between the mounted portion and the free end of the weight bar is equal to the total length of the weight bar.

Alternatively, the weight bar can be a telescopic rod or have multiple segments as described above with respect to the support member.

Alternatively, and/or additionally, the training apparatus can be provided as a set or kit comprising several support members and/or several weight bars of different lengths. The respective length adjustment can be made by exchanging the support member and/or the weight bar.

Preferably, the weight bar has a weight of at least 10 kg, preferably of at least 20 kg. Depending on the selected minimum weight of the weight bar, the stability of the support member can be adjusted in the case of a flexible support member.

Preferably, the weight bar has a total length of at least 1 m, more preferably of at least 1.5 m, more preferably of at least 2 m, more preferably of about 2.2 m. By varying the total length of the weight bar, the lever arm of the weight bar can also be adjusted. Furthermore, smaller weight bars provide smaller ranges of movement of the weight bar than longer weight bars, so that the range of movement can also be adjusted via the total length of the weight bar.

In an advantageous embodiment, the fastening member for fastening the support member to a support structure, preferably to an overhead support structure, comprises a displacement structure configured to allow displacement of the support member along the overhead support structure in at least one direction.

The displacement structure may include a rail that receives a portion of the support member or a component attached to the support member. Thus, the support member can be moved along at least one direction along the displacement structure, allowing for flexible positioning of the fitness apparatus in the room. As a result, the support member and the weight bar can be moved to a position in the room where the training apparatus is to be used. After the use of the training apparatus has ended, the support member and the weight bar can be conveniently pushed into a stowed position in the room that does not interfere with the training room or interferes with it only slightly.

The displacement structure preferably has a fixing means for fixing the support member in a position along the displacement structure.

This allows the support member to be fixed along the displacement structure, so that it is possible to prevent unintentional displacement of the support member along the displacement structure, especially during use of the training apparatus.

In an advantageous embodiment, the fitness apparatus further comprises at least one weight received by the weight bar.

In a further advantageous embodiment, the weight has at least one integrated locking means by means of which the weight can be locked in a position along the displacement section of the weight bar.

This allows the weight to be conveniently fixed to the weight bar without the additional use of a separate locking means, making it easier to load the weight bar with weights.

The weight bar may include another integrated locking means that interacts with the weight's integrated locking means to lock the weight in a position along the weight bar's displacement range.

For example, the locking means integrated in the weight may have at least one deflection member that can be deflected by the user actuating an actuating member on the weight. The weight bar may have, as a counter element, one or more openings into which the deflected deflection member engages when the user has slid the weight onto the weight bar, positioned the deflection member at the opening of the weight bar, and completed actuation of the actuation member.

In an advantageous embodiment, the weight is configured as a hollow cylinder with an outer diameter D and a length L, the length L being greater than the outer diameter D.

Typically, weights for use with a weight bar have a disc shape with an outer diameter that is substantially larger than the length of the weight. As a result, the weights have a relatively high radial extension from the weight bar, which is annoying for many exercises and can impair, in particular shorten, the motion sequence.

By providing a weight with a length L greater than the outer diameter D, the radial expansion of the weight is reduced, causing the weight to interfere with the motion sequence to a lesser degree.

The weight may be substantially disk-shaped.

The weight can be configured in different sizes and/or masses. Preferably, the weight can have a mass of 5 kg, 10 kg, 15 kg or 20 kg.

In an advantageous embodiment, the weight is locked against rotation about a longitudinal axis of the weight bar and/or against axial displacement of the weight along the longitudinal axis of the weight bar when the weight is received on the weight bar.

Such locking of the weight against rotation about a longitudinal axis of the weight bar and/or against axial displacement of the weight along the longitudinal axis of the weight bar can provide a secure fixation of the weight against movements of the weight on the weight bar. Such rotational and/or axial movements of the weight on the weight bar may impair the training effect when training with the fitness apparatus and/or may pose a physical hazard to the user of the fitness apparatus.

In another advantageous embodiment, the fitness apparatus comprises a receiving slide configured to be slid over and fixed to at least a portion of the weight bar and to at least partially receive the weight.

The receiving slide can be fixed against rotation about the longitudinal axis of the weight bar and against axial displacement along the longitudinal axis of the weight bar relative to the weight bar.

A locking member, for example a locking bolt, can be provided to fix the receiving slide to the weight bar. For this purpose, the receiving slide and/or the weight bar can have at least one opening which is/are designed to receive the locking member in order to fix the receiving slide to the weight bar relative to the weight bar. Preferably, the receiving slide and/or the weight bar may each have a plurality of openings arranged distributed along the longitudinal axis of the weight bar when the receiving slide is slid onto the weight bar. This allows the receiving slide to be fixed at different positions along the longitudinal axis of the weight bar.

The receiving slide may have at least one locking surface. The weight may include at least one counter-surface. The locking surface may cooperate with the counter-surface when the weight is received on the weight bar to substantially prevent rotation of the weight about the longitudinal axis of the weight bar.

By providing the above-described locking surface and counter-surface on the receiving slide and/or on the weight, which cooperate to substantially prevent rotation of the weight about the longitudinal axis of the weight bar, a simple and effective non-rotational fixation of the weight to the weight bar by means of the receiving slide is made possible.

The locking surface and the counter-surface can cooperate according to a key-hole principle. In such a principle, the weight may be received at least a predetermined first angle of rotation about the longitudinal axis of the weight bar relative to the receiving slide. At a second angle of rotation about the longitudinal axis of the weight bar relative to the receiving slide, the first angle of rotation being different from the second angle of rotation, the weight may be prevented from being received on the receiving slide.

In this way, rotation of the weight about the longitudinal axis of the weight bar, at least between the first angle of rotation and the second angle of rotation, can be substantially prevented.

Preferably, the first angle of rotation can differ from the second angle of rotation by 0° to 45°, preferably 0° to 30°, preferably 0° to 20°, more preferably 0° to 10°.

Since the locking surface and the counter-surface are formed on the receiving slide and/or on the weight itself, the non-rotational fixation is already provided by the reception of the weight on the receiving slide.

The locking surface may be formed on an outer periphery of the receiving slide.

The locking surface of the receiving slide and/or the counter-surface of the weight may be substantially flat.

The locking surface of the receiving slide and the counter-surface of the weight may be configured to substantially correspond to each other.

The counter-surface may at least section-wise define an opening formed in the weight, the opening being configured to be slid onto the receiving slide at least section-wise.

The opening is preferably formed substantially centrally in the weight.

Alternatively, the counter-surface may at least section-wise define a slot formed in the weight and configured to be slid onto the receiving slide at least section-wise.

The slot may extend from a substantially central point in the weight to an outer point relative to the central point.

The slot may extend from a substantially central point in the weight to an outer circumference of the weight.

This means that there is no need to attach additional locking members to secure the weight against rotation relative to the receiving slide. This facilitates the process of sliding the weights onto the receiving slide and/or the weight bar.

Preferably, the receiving slide has at least two locking surfaces and the weight has two counter-surfaces. The locking surfaces can cooperate with the counter-surfaces when the weight is received on the weight bar to substantially prevent rotation of the weight about the longitudinal axis of the weight bar.

Preferably, the locking surfaces and/or the counter-surfaces may be substantially parallel to each other. Alternatively, the locking surfaces may be arranged such that a first locking surface defines a first plane and a second locking surface defines a second plane, with the first plane intersecting the second plane in an angular range of from 1° to 90°, preferably from 1° to 70°, preferably from 1° to 50°, preferably from 1° to 30°, more preferably from 1° to 15°.

At least one of the locking surfaces of the receiving slide and/or at least one of the counter-surfaces of the weight may be substantially flat. Preferably, all of the locking surfaces of the receiving slide and/or all of the counter-surfaces of the weight are substantially flat.

In another advantageous embodiment, the fitness apparatus comprises an axial locking member configured to be slid onto at least a portion of the receiving slide and/or the weight bar and to lock the weight axially against the receiving slide to substantially prevent axial displacement of the weight along the longitudinal axis of the weight bar when the weight is received on the weight bar, the axial locking member having at least one counter-surface substantially corresponding to the locking surface of the receiving slide.

Preferably, the axial locking member has at least two counter-surfaces that substantially correspond to the locking surfaces of the receiving slide.

Preferably, the counter-surfaces can be substantially parallel to each other.

DETAILED DESCRIPTION OF THE EMBODIMENTS

FIG. 1 shows a schematic side view of a fitness apparatus 10. The fitness apparatus 10 includes a weight bar 12 having a longitudinal axis x, a total length L_(G), a free end 14, and a mounted portion 16. The weight bar 12 further comprises a displacement section 20 along which weights 18 can be slid on to the weight bar 12 to a desired position along the displacement range 20.

In the presently shown exemplary embodiment of FIG. 1 , the displacement section 20 extends from the free end 14 of the weight bar along the total length L_(G) of the weight bar 12. However, it is also conceivable that the displacement section 20 extends along a part of the total length L_(G) of the weight bar 12, for example over 30%, 50% or 75% of the total length L_(G) of the weight bar 12.

When the displacement section 20 does not extend along the total length L_(G) of the weight bar 12, the weight bar 12 may include a stop (see FIG. 2 ) disposed at a position along the length L_(G) of the weight bar 12 that prevents displacement of the weights 18 along a portion of the length L_(G) of the weight bar 12 extending from the stop to the mounted portion 16.

It is possible to adjust the lever arm extending from the position of the weight 18 at the displacement section 20 to the mounted portion 16 of the weight bar 12, and thus the training load of the training device 10, by moving the weights 18 along the displacement section 20. The further the weight 18 is positioned from the mounted portion 16, the greater the lever arm and consequently also the training load.

Accordingly, a large displacement section 20 of the weight bar 12 has the advantage that the training load of the training device 10 can be varied over a wide range.

FIG. 1 shows two weights 18 received by the weight bar 12. However, this is only an exemplary illustration. It is understood that a single weight 18 or more than two weights 18 may be received by the weight bar 12. Also, the form and design of the weight(s) may vary from the form shown.

The weight bar 12 shown in FIG. 1 has a uniform diameter, but this is also only an exemplary illustration. The weight bar 12 may also have different diameters along its length L_(G). For example, the mounted portion 16 may have a diameter that is smaller or larger than the diameter of the portion of the weight bar 12 disposed outside of the mounted portion 16.

Furthermore, the weight bar 12 may be hollow or solid.

The total length L_(G) of the weight bar 12 may be at least 1 m. For example, the weight bar 12 may have a total length L_(G) of 2.2 m, so that standard Olympic barbells may also be used as the weight bar 12.

In the illustrated embodiment, the fitness apparatus 10 further comprises two locking means 22 arranged on opposite sides of the weights 18 to fix the weights 12 at a position along the displacement section 20 of the weight bar 12. The locking means 22 may, e.g., be clamping members that can be clamped to the weight bar 12 to axially secure the weights 18.

However, it is also conceivable to provide only one locking means 22 for fixing the weight 18 at a position along the displacement section 20. On the one hand, this can be realized by providing a stop on the weight bar 12 (see FIG. 2 ). Alternatively, this may be realized by providing at least one of the weights 18 with, for example, an integrated locking means 22 that cooperates with a counter means provided on the weight bar 12. The counter means may, for example, include an opening into which the locking means 22 integrated with the weight 18 engages to fix the weight 18 at a position along the displacement section 20. The integrated locking means 22 may be actively operable by the user, e.g., by means of an actuating member disposed on the weight 18.

However, a passively actuated locking means 22 is also conceivable, which is provided with a spring, for example. The spring can be deflected together with the locking means 22 When the weight 18 is slid onto the displacement section 20 of the weight bar 12, the spring may be deflected together with the locking means 22. When the weight 18 has been slid on up to the counter means of the weight bar 18, and the locking means 22 is positioned adjacent the opening of the weight bar 18, the spring is released so that the locking means 22 engages with the opening and fixes the weight 18 to the displacement section 20 of the weight bar 12.

At its mounted portion 16, the weight bar 12 is received in a bearing member 24. The bearing member 24, which is shown only schematically in FIG. 1 , may comprise, for example, a ball bearing or a slide bearing to allow rotation of the weight bar 12 about its longitudinal axis x. This rotational movement about the longitudinal axis x of the weight bar 12 is indicated in FIG. 1 by the movement plane R3. However, a bearing of the weight bar 12 in the bearing member 24 fixed against rotation about the longitudinal axis x is also conceivable. In this variant, it is preferred that the grip region of the weight bar (not shown), be designed so as to be rotatable. This can be achieved, for example, by means of a sleeve-shaped grip region which is rotatable about its or the longitudinal axis of the weight bar. As described, a bearing at the end by means of ball bearing and housing, slide bearing is also possible.

It is also conceivable that the weight bar 12 is slidably mounted in the bearing member 24, so that the weight bar 12 may be slid along its longitudinal axis x beyond the bearing member 24 in order to adjust the length of the weight bar 12 extending between the free end 14 and the mounted portion 16 of the weight bar 12. This length thus deviates from the total length L_(G) of the weight bar 12 in the above-described pushed-through state of the weight bar 12. For example, the lever arm of the weight bar 12 and thus also the training load of the training apparatus 10 may likewise be adjusted in addition to, or as an alternative to, displacement of the weight 18 along the displacement section 20 of the weight bar 12 or by selection of the total length L_(G) of the weight bar 12.

The bearing member 24 may further comprise a fixing member, by means of which the weight bar 12 may be axially fixed in the bearing member 24 to prevent unintentional displacement of the weight bar 12 in the bearing member 24.

The fitness apparatus further comprises a support member 28 having a longitudinal axis y, a first, upper end 30 and a second, lower end 32, with a length L_(H) of the support member 28 extending between the two ends 30, 32. The first end 30 of the support member 28 is attached to an overhead support structure 35, which in the embodiment shown in FIG. 1 is a ceiling structure of a room, by means of an fastening member 34. The second end 32 of the support member 28 is connected to the bearing member 24.

In the exemplary embodiment shown in FIG. 1 , the support member 28 is designed as a bar. In particular, the support member 28 may be configured as a rigid bar. However, it is also conceivable that portions of the support member 28 which is configured as a bar may be movable relative to other portions of the support member 28. For example, a portion of the support member 28 may be rotatable relative to another portion of the support member 28. Further, a portion of the support member 28 may be axially displaceable relative to another portion of the support member 28, for example in the form of a telescoping rod. It is understood, as described at the outset, that a flexible support member, for example a rope or belt, may also advantageously be used in place of the bar.

The length L_(H) of the support member 28 is preferably at least 100 cm to provide the mounted portion 16 of the weight bar 12 at a height that allows a plurality of overhead exercises and exercises performed below the eye level of the user.

In the exemplary embodiment shown in FIG. 1 , the weight 18 rests on the ground 33 of a room in which the fitness apparatus 10 is arranged. However, this is only an exemplary representation that depends on the selected length L_(H) of the support member 28. It will be understood that a shorter length L_(H) of the support member 28 may be selected, where the weight 18 does not rest on the ground 33. Preferably, the lower end of the support member 28 is positioned about 40 cm to 120 cm above the ground. However, the exact position will depend on the notified exercise and the size of the user or group of users. Preferably, this height is adjustable, preferably by adjusting the length of the support member 28.

In the embodiment shown in FIG. 1 , the free end 14 of the weight bar 12 may be moved in two planes about the bearing member 24. First, the weight bar 12 may be swiveled in a plane that is perpendicular to the longitudinal axis y of the support member 28 (horizontal plane). This movement plane is marked R₂ in FIG. 1 . Furthermore, the weight bar 12 may be tilted in a plane in which the longitudinal axis y of the support member 28 extends (vertical plane). This movement plane is marked R₁ in FIG. 1 . It is understood that the mobility of the free end 14 of the weight bar 12 can be realized in such a way that the free end 14 of the weight bar 12 may be movable in only one of the two movement planes R₁, R₂ at a time or simultaneously in both movement planes R₁, R₂ as a combined movement.

Mobility in the movement plane R₂ can be realized, for example, by the fastening member 34 having a swivel joint, for example in the form of a swivel joint carabiner. Additionally, or alternatively, the bearing member 24 may have a swivel joint to allow movement in the movement plane R₂. Also, this mobility may be ensured by the flexibility of the support member 28.

The mobility in the movement plane R₁ may be realized, for example, by the bearing member 24 and/or the joint 34 and/or the support member 28 allowing tilting of the weight bar 12.

The exemplary embodiment shown in FIG. 2 is substantially the same as the exemplary embodiment shown in FIG. 1 . In contrast to the exemplary embodiment shown in FIG. 1 , the weight bar 12 has a stepped structure with different diameters, thereby forming a stop 36 between two portions of the weight bar 12 having different diameters, against which stop the weight 118 received on the weight bar 12 abuts. Accordingly, the fitness apparatus 10 comprises only one locking means 22 which axially fixes the weight 118 against the stop 36.

Consequently, in contrast to the exemplary embodiment shown in FIG. 1 , the displacement section 28 does not extend over the entire length L_(G) of the weight bar 12, but over approximately 50% of the length L_(G) of the weight bar 12.

Further, in contrast to the weight 18 shown in FIG. 1 , the weight 118 has an elongated shape with an outer diameter D and a length L_(Z), the length L_(Z) being greater than the outer diameter D. This reduces the radial extent of the weight 118, which in turn at least reduces the interference of the weight 118 with the motion sequences.

FIG. 3 shows another embodiment of a fitness apparatus 10 according to the invention.

In contrast to the embodiments shown in FIGS. 1 and 2 , the support member 28 is configured as a flexible band. However, it is also conceivable to use a rope or a chain as flexible support member 28. As already described, such a flexible support member may also be used in the embodiments according to FIG. 1 or 2 .

The use of a flexible support member 28 allows the weight bar 12 to have a high number of degrees of freedom. In the present embodiment, the weight bar 12 is configured as a rigid body. Consequently, due to the flexible properties of the support member 28, the weight bar 12 has the maximum number of six degrees of freedom of a rigid body in space.

The possible degrees of freedom include the movement planes R₁, R₂, and R₃ shown in FIGS. 1 and 2 . These movement planes R₁, R₂, and R₃ can be realized alone by the flexibility of the support member 28 without the additional provision of articulated or swivel joints. When pivoting the weight bar 12 in the (horizontal) movement plane R₂, the support member 28 is twisted due to its flexible properties, so as to allow movements in the movement plane R₂. On the other hand, when the weight bar 12 is tilted in the movement plane R₁, the support member 28 is bent along its longitudinal axis y and/or about an axis perpendicular to the longitudinal axis y, so as to allow movements in the (vertical) movement plane R₁. When the weight bar 12 is rotated about its own longitudinal axis x in the movement plane R₃, the flexible support member 28 may also be bent about its longitudinal axis y provided that the joint 24 or the grip region does not allow rotation.

However, in order to further increase the mobility of the fitness apparatus 10 and to reduce the load on the support member 28, for example due to the torsional load arising at the support member 28, articulated and/or swivel joints may additionally be provided in the bearing member 24 and/or on the fastening member 34. For example, one or both of the bearing member 24 and the fastening member 34 may be configured as a universal joint or ball joint.

Furthermore, the weight bar 12 can also be moved in all three translational directions, which are marked T₁ to T₂ in FIG. 3 . These degrees of freedom are also made possible by the flexible properties of the support member 28 and/or the specific design of the bearing member 24 and the fastening member 34.

Further, in the representation according to FIG. 3 , the bearing member 24 comprises a housing 26. The second end 32 of the support member 28 is connected to the housing 26 of the bearing member 24. However, it is also conceivable to dispense with the housing 26 and to attach the support member 28 directly to the component of the bearing member 24 supporting the weight bar 12.

The housing 26 may have a minimum weight, preferably 5 kg or 10 kg, which has the advantage that the flexible support member 28 is stabilized by the weight force of the housing 26 acting on the support member 28. Consequently, the stability of the support member 28, i.e., the deflection sensitivity of the support member 28, can be influenced via the adjusted weight of the housing 26. The weight of the housing thus functions as a leveling counterweight. However, it does not have to be provided as the housing 26 but may also be attached to the support member 28 as a separate leveling counterweight.

The housing 26 and/or the support member 28 may additionally, or alternatively, comprise a receiving member (not shown) for receiving additional leveling counterweights to increase the total weight of the housing 26 or of the support member, respectively, beyond the dead weight thereof. In this way, the total weight of the housing 26 or of the support member, respectively, can be adjusted in a simple manner.

The support member 28 preferably further includes a length adjustment mechanism 38 at its second end 32, which allows adjustment of the length L_(H). Thus, the length L_(H) of the support member 28 can be shortened accordingly so that the position of the weight bar 12 may be adjusted to accommodate different body sizes, different room heights, and/or different exercises, for example, overhead exercises or exercises performed substantially below the eye level of the user.

For example, the length adjustment mechanism 38 may include a buckle through which the flexible support member 28 may be pulled. The portion of the support member 28 that is pulled through the buckle thus represents a loose portion of the support member 28 by which the length L_(Z) of the support member 28 is reduced. The length adjustment mechanism 38, for example comprising a buckle, may, in particular, be integrated in the flexible support member, e.g., band or belt, 28.

Alternatively, the length adjustment mechanism 38 may be formed on the bearing member 24, the housing 26, or the fastening member 34.

FIG. 4 shows another embodiment of a fitness apparatus 10 according to the invention.

According to the exemplary embodiment shown in FIG. 4 , the fitness apparatus 10 may comprise an elastic band 40 that may be connected to the weight bar 12 by means of a fixing member 42. The elastic band 40 may be fixedly connected to the ground 33 of a room at a fixing anchor 44. Alternatively, the elastic band may be connected to a side wall or another stationary structure. One band or more may be used.

As shown in FIG. 4 , the elastic band 40 may be used in place of a weight as a resistance against which the user moves the weight bar 12. However, it is also conceivable to provide the elastic band 40 in combination with one or more weights 18, 118 received on the weight bar 12.

Furthermore, it is also conceivable to attach the elastic band 40 directly to the weight bar 12 and thus to dispense with the additional fixing member 42.

The elastic band 40 may be a band having two ends, a first end being connectable to the weight bar 12 and a second end being connectable to the fastening anchor 44.

Alternatively, the elastic band 40 may be an endless band which, e.g., with one portion may be looped around the weight bar 12 to connect the elastic band 40 to the weight bar 12. At another portion of the elastic band 40 configured as an endless band, the elastic band 40 may be connected to the fastening anchor 44 by, for example, looping a portion of the elastic band 40 around the fastening anchor 44.

The fixing member 42 may be fixed to the weight bar 12 immovably relative to the weight bar 12. However, it is also conceivable to realize the fixing member 42 in such a way that it is displaceable along at least one portion of the weight bar 12 along its longitudinal axis x. In addition, the fixing member 42 may have a locking means that can optionally achieve a non-displaceable fixing of the fixing member 42 to the weight bar 12.

The fastening anchor 44 may be a releasable member comprising, for example, an annular or partial annular connecting member for connecting the elastic band to the fastening anchor 44. For example, the fastening anchor 44 may be attachable to a structure of the ground 33, if required, such as in an opening formed in the ground 33, for example by screwing in or plugging in.

Furthermore, it is conceivable to attach the fastening anchor 44 to a displacement structure on, or in, the ground 33, which allows a movement of the fastening anchor 44 parallel to the ground 33. This displacement structure may, for example, be in the form of a rail in which the fastening anchor 44 can be moved in the room in at least one direction.

The fastening anchor 44 may also be fastened to a structure other than the ground 33, such as a side wall or ceiling of the room, or to a movable object arranged in the room.

The length of the elastic band 40 can be varied to provide different resistances to be overcome by the user.

Providing an elastic band allows for a further refinement of the training options, especially in the context of functional training.

FIGS. 5 to 9 show a disc-shaped weight 218, a receiving slide 230 and an axial locking member 244. However, the disc shape of the weight 218 shown in FIGS. 5 and 6 is only exemplary. Other possible shapes of the weight 218 are also conceivable, for example a polygonal and/or cylindrical shape.

FIGS. 5 and 6 show multiple weights 218 of different sizes. However, it is also conceivable to attach a plurality of weights 218 of the same size or only a single weight 218 to the receiving slide 230.

The weight 218 includes an opening 220 through which the weight 218 can be slid onto a weight bar, e.g., the weight bar 12 shown in FIGS. 1 to 4 , at least section-wise.

The opening 220 is arranged substantially in the center of the weight 218 and extends outwardly in a slot-like manner to an outer circumference of the weight 218.

The weight 218 comprises a further elongated opening 222 extending decentralized in a circumferential direction along a portion of the weight 218. The opening 222 may facilitate gripping and transporting of the weight 218 by a user.

The receiving slide 230 includes a substantially central opening 232 through which the receiving slide 230 can be slid onto at least a portion of a weight bar, such as the weight bar 12 shown in FIGS. 1 to 4 .

The opening 232 extends completely through the receiving slide 230 along a longitudinal axis of the receiving slide 230. In this way, the receiving slide 230 may be slid onto a relatively large portion of a weight bar to allow a high variability in positioning the receiving slide 230 along the longitudinal axis of the weight bar.

The receiving slide 230 also includes a receiving section 234 and a stop section 240.

The stop section 240 may be used to provide an axial stop surface for the weight 218 to limit axial displaceability of the weight 218 along the longitudinal axis of the weight bar in at least one direction along the longitudinal axis of the weight bar.

The receiving section 234 of the receiving slide 230 may serve to receive weights 218 via the opening 220 thereof. The receiving section 234 includes a plurality of openings 236 distributed along a longitudinal axis of the receiving section 234. The longitudinal axis of the receiving section 234 may substantially correspond to the longitudinal axis of the weight bar when the receiving section 234 is received on the weight bar.

The receiving slide 230 includes a fixing mechanism 242 for axially fixing the receiving slide 230 to the weight bar. The fixing mechanism 242 may include a locking pin received in an opening of the receiving slide 230 and cooperating with at least a portion of the weight bar, for example, via at least one opening provided in the weight bar with which the locking pin may engage, or via a surface of the weight bar with which a locking pin or other fixing member may engage.

The receiving slide 230 has two substantially parallel locking surfaces 238 (see FIG. 8 ). The weight 218 has two counter-surfaces 224 substantially parallel to each other.

The weight 218 may be aligned such that the counter-surfaces 224 are substantially aligned with the locking surfaces 238, preferably in parallel, so as to then be slid onto the receiving portion 234. Thus, the locking surfaces 238 and the counter-surfaces 224 cooperate according to a key-and-hole principle to allow the weight 218 to be slid onto the receiving section 234 in the above-described orientation relative to each other, but to substantially prevent rotation of the weight 218 about the longitudinal axis of the weight bar or about a longitudinal axis of the receiving slide 230, respectively, when the weight 218 is slid onto the receiving section 234.

The receiving slide 230 may also comprise one locking surface 238 only or it may comprise more than two locking surfaces 238.

The locking surfaces 238 interact with the counter-surfaces 224 when the weight 218 is received on the weight bar to substantially prevent the weight 218 from rotating about a longitudinal axis of the weight bar.

In this way, the weight 218 may be locked against rotation about the longitudinal axis of the weight bar by means of the receiving slide 230.

In FIGS. 5 to 8 , the locking surfaces 238 and the counter-surfaces 224 are formed substantially parallel to each other. Alternatively, the locking surfaces 238 may extend at an angle to each other. The counter-surfaces 224 may also extend at an angle to each other.

The axial locking member 244 also comprises two counter-surfaces 248 which substantially correspond to with the locking surfaces 238.

Thus, the axial locking member 244 may be oriented such that the counter-surfaces 248 are substantially parallel to the locking surfaces 238 so as to then be slid onto the receiving section 234. Thus, the locking surfaces 238 and the counter-surfaces 248 may likewise cooperate with each other according to the above-described key-hole principle.

The axial locking member 244 comprises an opening 246, shown as a dashed line in FIG. 9 . The opening 246 may receive a fixing n member. The fixing member may at least partially engage with one of the openings 236 formed in the receiving section 234. This allows the fixing of the axial locking member 244 to a portion of the receiving slide 230, preferably against rotations about the longitudinal axis of the weight bar and/or axial displacement of the axial locking member 244 along the longitudinal axis of the weight bar.

By interaction of the locking surfaces 238 of the receiving slide 230 with the counter-surfaces 224 of the weight 218 and the axial fixing action of the axial locking member 244 it is possible to lock the weight 218 against rotation about a longitudinal axis of the weight bar and against axial displacement of the weight 218 along the longitudinal axis of the weight bar when the weight 218 is received on the weight bar.

This may substantially prevent rotation of the weight 218 about the longitudinal axis of the weight bar and axial displacement of the weight 218 along the longitudinal axis of the weight bar.
